hasjamong its objects andadvantages thev pro-V vision Vof an improved' c'oil for heatingl water.

The invention is applicable to boilers of convert-` `tional design and may beassociatedyvitnsueh boilersrafter installation. InA addition, I providea novel valve mechanism for. regulating the .ow. of Water through the coils 's'o that Water? maybe heated in accordance with variableht Water.` demands.` A furtherffeature'resides inthe provision of an improvedbloW-oi structure Vpermitf ting effective cleaningof the coil and valve.'struc-1 ture.y In the accompanying drawing: Fig. l1 isan elevation of a steam boiler of conventional design embodying the invention;A

This tank is provided with the usual cold Water feed pipe; I4, hot water supply pipe I6, and blow-off pipe I8.' 'I'he hot water. feed pipe 28 for the storage tankj I2 is connected with a coil valve 22 mounted upon 'the end 2 4 of the' boiler. Cold Water passing A through thestorage; tank I2'is delivered tothe coil valve` 2 2 through the medium of a pipe 26, and normally'ciijeulates through coils 28 and 3Ilpositione d 1Within'the boiler Ibefore it is delivered vto vthe hotfwater storage tank I2. f"

My coil valve 22 confiprisesfadrum 32 having an open end closed by a cover"3.4;throughl the medium of bolts 36. One end o fthe drum isfprovided with a threaded 'neck 38 Yscrewed:into a' threaded flange 48 rivetedto the boiler :shell 24jA by'rivet`s42. Ofcourse,the-i'langef'4ll may be; welded to the shell instead" of riveted thereto as;

shown.' "Either type of fastening permits the coil valve 22 to be easily mounted upon the boiler by merely cutting an opening 44 in the boiler shell and securing the ange 48 in place. In Fig. 1, I illustrate the coil valve 22 as being positioned to one side of the vertical center line of the boiler to permit another unit to be mounted upon the boiler.

Three partitions 46, 48, and 50 separate the drum 32 into three compartments 52, 54, and 56.

The partitions larecast integrally with the drum 32 *and a valveIcylinder 58. Both thecoils 28 and 38 are U-shaped; .In Figs. 3 and 4, I illustrate the ends of .the coil 28 as being anchored Within openings in the neck 38, whichendsgcom- 6,;- municate with the `compartments 52 and 54. Similarly, the endsof the coil 30 are anchored` Within vopenings 62 in the neck 38 and communi` cate4 with lthe compartments `54 `and 56.., Water fromthe pipe..26 `enters the compart- 10x1 ment 52,- passes through the coil 28 and into'. the compartment 54.` Normally, the valvefplug`v 64 is positione'dior closing the `opening 66 in the valve cylinder 58 so that the water entering theV compartment 54iiows through the coil-30 intovlgr; the compartment 56an'd to the hot Water storage tankf I2 Referring to Fig. 3, the valveplug 64 is provided4 with a shaft 68 passing through aA packing gland 1I) -on the cover 3 4 and provided with a grip member 12. I Imount a, pointer 'I4 upon the shaft 68 to-indi cate various adjusted positions of ,the valvefplug 64, as indicated by thejindicia '16, see. 5.. In I Fig. 1, Iindicatethe level of the water in the" boilevrat 18, so Vthatthe `coil 3U lies in a plane 2.5. above the water level and is influenced by Vthe temperature of the steam above the water. Inl this Way, I makeV use of the higher temperature of the steam during that part of the year when a'small fire is maintained in the boiler. Less iirej 8pt is required in the boiler for heating water. How# ever, dtu'ing cold weather a larger re is maintained in the boiler. Under such conditions, the level 18 is raised to submerge the coil 38 and to prevent overheating of the water passingthrough 8:5,-v thecoils, in addition to providing protection4 for. the tubing and the reduction of scale formationf therein. I I

During the high temperature period ofV use, it'maybe that thewater supply would become 4Q overheated., To preventsuch fan occurrence,"A it may be desirable to shunt some of the Water.v entering the coil drum 22 around one ofthe tubes."4 maybel accomplishedlby adjustingthe valve and communicating with lthe compartment 54. In Fig. 1, I illustrate the pipes and 26 as being provided with valves 88 and 90, respective- Y ly. With the plug 64 adjusted to ,close the ropening 66, I clean the Vvalve 28 by opening the blow-ovalve 84 and keepingV the valve 90 open to permit thewwater under` pressure directed to the pipe 26 to flowV into the chamber 52 through Y the Vcoil'28into the compartment, 54, and outof the system through' thepipe 86.1' Sirr1 'i1ariy; the tube of Athe.coil3il'mayY be cleaned by vopening the blow-off valve 84 and keeping the valve 88 open to permit lwater under pressureV to flow int' the compartment 56 through the coillinto the compartment 54 and. out ofthe systemthrough`l` the piper86.
